My only sorrow regarding jetliners--which I'm sure cuts no ice with the accountants, but to me is an aesthetic loss--is that they all fit just one "formula" now (a cylindrical fuselage with moderately-swept wings and tail surfaces, with two wing-mounted high-bypass engines), while T-tails, rear-mounted engines, low-bypass turbofans (I remember *turbojet*-powered airliners, like the Convair 880 and early 707s and DC-8s) and three- and four-engine variations become rarer as those aircraft are withdrawn from service.

True....but "you canna change the laws of physics".....and when the requirements are similar and what you have to work with is similar the you get basically the same answer.

I hope so. Another big driver in the configuration of commercial airplanes (and which is an obstacle to flying wing/blended wing-body configurations) is the requirement to be able to get everyone out of the airplane in 90 seconds with half of the doors inoperative and with while keeping them far enough from engines that might still be operating as well as far enough from each other to fairly evenly split up the escaping traffic. That drives where the doors are and how big they are among other things. And of course those doors are openings in the pressure vessel which must not be allowed to open in flight (usually done by making them "plug" doors). But distributed propulsion and new materials should open up the "design space" some. It will be fun to watch.

Perhaps the closest things to BWB airliners that have flown were Vincent Burnelli's various "quasi-flying wing" aircraft, which (unintentionally) demonstrated almost miraculous crash survivability, because the "wing/fuselage" center section was structurally a box girder. Business jet- and regional jet-size BWB planes might meet the passenger evacuation requirements. Distributed propulsion electric ducted fan airliners with "thrusting/lift-augmenting 'slot' nozzles" (I've seen a NASA CGI video of a proposed BWB cargo plane of this type) look like the Horten brothers' elegant swept flying wings.

Cars/Trucks are no longer designed/built for serviceability by the "outhouse mechanic" nor will they ever again be.
Too many specialized tools are required and automobiles no longer require service as frequently. The Porsche. Boxster is the most extreme example of this. My understanding is that you have to lift the entire body off to change the spark plugs.. My C6 is an example of extremely easy serviceability. Everything is easy. Easiest car to work on I have ever owned. No joke.

Typical friggin' moron engineer's attitude for explaining their sh!tty designs... "Outhouse' mechanic's hands and range of motion and flexibility is the same as a factory mechanic... Boxter-- meh... if you've got money to waste on that POS, well, you can $2 grand for a friggin tuneup... a fool and their money are soon parted. Meh, I don't like the new vehicles period. Too much BS... all show, no go... "all hat and no cows". I'm keeping my 15 year old (newest) vehicles and just fixing them as I need to... and I think my next farm truck will probably be an early-mid 90's diesel... Later! OL J R

My car (C6 Corvette) is ALL GO and plenty of show.
Top speed over 190 mph, quarter mile in under 12sec, 0-60 in 4 sec, and handles like a go-cart. Easy to work on and parts very reasonably priced. Best of all, only TWO SEATS- NO room for BRATS !!!!
